Please note that this item is sold as "for parts or not working" and has some damage.

Citronic Neolith Portable Column Array Pa Speaker & Covers Mains / Battery 1200w.

Note:

bass speaker has no output, has not been opened to check weather its a speaker problem or component, however top column arrays speaker play tops and midrange frequencies which means the amplifier section is working 

so maybe either a blown driver or a blown fuse / resister 

 and there is a slight crack cracked/break on plastic on connection point of one of the tower units

however it does not affect play as its cosmetic and damage is damage 

Again so no confusion sold as spares and repairs with no return accepted for this reason

happy to send a video of this before posting  showing working with relevant faults described

mids tops frequencies play only but no bass output 

Original box supplied with Manual and mains cable
